Hi, I was hoping I was ready to start printing now. But doing some test prints now I notice a few issues I do not like. First think I noticed was this strange knocking/clicking sound. I found It comes from the Z motors / shafts. It looks like I got a lot of Z motion printing a single layer. I feel they almost shudder when they click back and forward adjusting Z. Then I think about I have not seen any actual leveling of the bed in the build manual anywhere. I do not think about the mesh level that I did but adjusting the screws in each corner. Lumpy feel on the Y axis when I move it manually. It was super smooth before tightening everything. Over extruding! Using 0.8mm nozzle on E0. I downloaded @Alex9779 fw from https://jenkins.alitecs.de/job/BigBox_Dual-RC/. Should I not have two E step configuraions? From M503 I have E304 at the moment.
